Takeshi Yoroi

Yoroi Takeshi (鎧武士) also known as Hurricane Polymar (破裏拳ポリマー) is the main protagonist of the series.

Onigawara, the director of the International Secret Police Agency, looked forward to making Takeshi a top-notch criminal investigator. Takeshi was given training, which turned him into an all-around sportsman as well as martial arts expert. However, Takeshi's attitude toward crime-fighting was so incompatible with Onigawara's, that he disowned him. For a while Takeshi investigated crime alone; then he became a private detective's assistant and general handyman. Secretly, however, Takeshi obtained from a scientist a new artificial polymer, polymet, that was far stronger than steel. With this polymet Takeshi transformed himself into Hurricane Polymar, an invincible costumed hero.

He is a highly skilled martial artist, trained in the art of Ha Ri Ken (Internal Destructive Fist) Karate. When wearing his suit he has superhuman speed, strength, & agility, and he is immune to bullets, heat, and poisonous gasses. His suit is made of memory plastic which enables him to assume any shape, each which is stored in his helmet's memory. Among the different shapes are the Polymar Machine (race car), Polymar Drill (underground burrowing vehicle), Polymar Hawk (jet), Polymar Grandplus (submarine), and Polymar Roller (tank).
